What is EEXI?

The Energy Efficiency Existing Ship Index (EEXI) is a mandatory design standard adopted under MARPOL Annex VI, applying to all vessels of 400 GT and above. It provides a benchmark for a ship’s fuel efficiency — similar to energy labels on new cars. While EEXI evaluates design efficiency, actual performance depends on operational choices (see EEOI and CII).

The EEXI is based on the IMO’s Energy Efficiency Design Index (EEDI), which came into force for newbuilds from January 2013. EEXI extends these standards to older vessels by enabling a retroactive assessment of their design efficiency.

 

How to Comply with EEXI

Shipowners must certify that the required reduction in CO₂ emissions per tonne-mile (gCO₂/tonne-nm) has been achieved for the vessel’s type and size. The most common method of compliance is Engine Power Limitation (EPL) — reducing the maximum engine output to limit emissions.

Compliance is demonstrated via your class society or Flag State, following the first MARPOL survey after 1 January 2023. Once the EPL or chosen measure is installed, verified, and certified, a new International Energy Efficiency Certificate (IEEC) is issued.
No further action is required under this regulation once certified.

 

Common Solutions for EEXI Compliance

  • Engine Power Limitation (EPL / SHaPoLi)
  • Wind assistance technologies
  • Propeller or hull form optimisation
  • Waste heat recovery
  • Reduced electric consumption

 

Baltic Exchange Position & Support

The Baltic confirms that all Baltic standard vessels are operated in compliance with applicable regulations, including EEXI. Our analysis shows that engine power limitation and related measures do not materially impact vessel operations in today’s market.

Baltic Exchange also provides:

  • Standardised EEOI benchmarks for performance comparisons
  • Emissions tools and calculators to support informed decision-making

 

EEXI: Ongoing Development

EEXI regulations remain under ongoing review at the IMO during bi-annual MEPC meetings. Amendments, clarifications, and future alignment with long-term decarbonisation goals may be discussed.
